云取证综述

云计算的出现和发展,给人们带来了诸多便利。云用户只需投入很少的开销,就能获得大量的计算资源和云存储空间。但云计算本身资源共享的特性也导致了许多安全方面的隐患,比如为传播恶意程序提供了便利、用户隐私数据更易泄露、数据更易被破坏等等。为保证云环境的健康发展,针对云犯罪展开取证分析(即云取证)显得尤为重要。对于云取证这一新兴领域,本文首先介绍了其概念以及当前该领域面临的技术、法律问题。然后重点介绍了目前云取证领域已经取得的研究成果。最后,比较分析了现有工作的优缺点并提出了云取证领域的机遇。

Cloud Forensics

Cloud computing becomes more and more popular due to its convenience, flexibility, low cost and fast speed. Users can get a lot of computer resources and storage space at low cost. However, the security risk, such as the spreading of illegal information, sensitive data leakage, data tampering, is still crucial problem in cloud computing environment. Hence, the forensics of cloud computing crime becomes particular important. Firstly, this paper introduces the concept of cloud forensics and it lists the technical and legal challenges in could forensics. Then researches by now in cloud forensics are introduced and analysis summary on current researches is presented. Finally, opportunities of cloud forensics are put forward.
